P0122 Code Nissan:
The P0122 code in a Nissan indicates that there is a problem with the throttle position sensor or switch circuit. Specifically, it means that the voltage signal from the sensor is lower than expected, indicating that the throttle is not opening as much as it should be. This can cause a variety of issues, including poor acceleration, stalling, and even difficulty starting the vehicle. To fix this issue, the throttle position sensor or switch will need to be inspected and potentially replaced. It is also important to check the wiring and connections to ensure that there are no issues there as well.
What are the Signs or Symptoms of P0122 Code in Nissan?
The P0122 code in Nissan indicates a problem with the Throttle Position Sensor/Switch ‘1’ Circuit Low Input. This code is usually triggered when the voltage signal from the throttle position sensor falls below the expected range. Here are some of the common signs and symptoms of the P0122 code in Nissan:
- Check Engine Light: The most common symptom of the P0122 code is the illumination of the check engine light on the dashboard. This light indicates that there is a problem with the engine or emissions system.
- Reduced Engine Power: Another common symptom of the P0122 code is reduced engine power. The engine may not respond as quickly or as powerfully as it should, which can make it difficult to accelerate or maintain speed.
- Stalling: In some cases, the engine may stall or shut off completely when the P0122 code is triggered. This can be dangerous if it happens while driving, as it can cause a loss of control over the vehicle.
- Difficulty Starting: The P0122 code can also make it difficult to start the engine. The engine may crank but not start, or it may start but then stall shortly after.
- Poor Fuel Economy: If the P0122 code is not addressed, it can lead to poor fuel economy. This is because the engine is not running as efficiently as it should, which can cause it to use more fuel than necessary.
If you notice any of these symptoms in your Nissan, it is important to have the vehicle inspected by a qualified mechanic as soon as possible. Ignoring the P0122 code can lead to more serious problems down the road, and can even cause damage to the engine or other components of the vehicle.This response was truncated by the cut-off limit (max tokens).

P0122 Code Nissan:
If you own a Nissan and your check engine light has come on, you may have a P0122 code. This code indicates that there is a problem with the throttle position sensor/switch ‘1’ circuit, specifically that there is a low input signal. This can cause a variety of issues with your vehicle’s performance, including poor acceleration, stalling, and even difficulty starting.
- Faulty Throttle Position Sensor – The most common cause of a P0122 code is a faulty throttle position sensor. This sensor is responsible for monitoring the position of the throttle and sending that information to the engine control module (ECM). If the sensor is not working properly, it can cause a low input signal and trigger the P0122 code.
- Wiring Issues – Another possible cause of a P0122 code is wiring issues. If there is a problem with the wiring that connects the throttle position sensor to the ECM, it can cause a low input signal and trigger the code. This can be caused by damaged or corroded wiring, loose connections, or other issues.
- ECM Problems – In some cases, the problem may not be with the throttle position sensor or the wiring, but with the ECM itself. If the ECM is not functioning properly, it may not be able to receive the signal from the throttle position sensor, which can trigger the P0122 code.
- Other Issues – There are a few other issues that can cause a P0122 code, although they are less common. These include a faulty accelerator pedal position sensor, a vacuum leak, or a problem with the throttle body.
If you are experiencing a P0122 code, it is important to have your vehicle diagnosed by a qualified mechanic. They will be able to determine the exact cause of the problem and recommend the appropriate repairs. In some cases, the issue may be as simple as replacing a faulty sensor or repairing a damaged wire. In other cases, more extensive repairs may be necessary.
Ignoring a P0122 code can lead to further damage to your vehicle and can even be dangerous if the issue causes your vehicle to stall or have difficulty accelerating.
Fixes for P0122 Code Nissan
The P0122 code in Nissan vehicles indicates a problem with the throttle position sensor/switch circuit. This code is triggered when the engine control module (ECM) detects a low input signal from the throttle position sensor (TPS) or switch.
Here are some possible fixes for the P0122 code:
- Replace the TPS: The most common cause of the P0122 code is a faulty TPS. If the sensor is not working properly, it can send a low input signal to the ECM, triggering the code. Replacing the TPS should fix the problem.
- Check the wiring and connections: Sometimes, the problem may not be with the TPS itself, but with the wiring or connections leading to it. Check for any damaged or corroded wires, and make sure all connections are secure and free of debris.
- Replace the ECM: In rare cases, the problem may be with the ECM itself. If all other components check out, the ECM may need to be replaced.
- Clean the throttle body: A dirty or clogged throttle body can also cause the P0122 code. Cleaning the throttle body can help improve the TPS signal and fix the problem.
- Check for vacuum leaks: Vacuum leaks can cause a variety of engine problems, including a low TPS signal. Check for any leaks in the vacuum system and repair as necessary.
If you are experiencing the P0122 code in your Nissan vehicle, it is important to address the issue promptly to avoid further damage to your engine. Consult with a qualified mechanic or Nissan dealership to diagnose and fix the problem.
